. clear, and exact description.

This invention relates to multiple totalizer cash registers and among the objects of the-invention are to provide an improved differential mechanism for accounting machines comprising an extremely simple construction without springs, for converting an invariable movement into any desired differential movement. Another object of the invention is to provide an adjustable differential mechanismwhich, after operation, is automatically returned to its adjusted position in condition to repeat the same operation without readjustment. i

Another object of the invention is to pro-l vide a lever set cash register having a plurality of totalizers with an improved differential mechanism for operating the totalizers.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements' of which are set forth in appended claims, and a preferred' form of embodiment of which is hereinafter described with reference'to the drawings which accompany and form part of the specification.

Fig. 7 is a top plan view of the differential mechanism for actuating the multiple totalizers.

.The invention as herein described is embodied in a lever set multiple totalizer cash register and is shown as applied to the single totalizer machine yfully described and shown in the United States Thomas Carroll No. 751,611.

Patent to The patent vshows a machine having a plurality of differentially movable segmental setting levers provided Vwith teeth meshing with pinions rigidly connected to type carriers. Individual items are therefore set in the type carriers according to differential movement of the levers. The levers also mesh with racks having teeth, more or less 7^-f which, by movement of the levers, are set in the path of a movable total-izing device, for the pur pose of-causing the totalizing device to-be differentially rotated as desired when moved over the racks.

In the application of the present invention the setting levers, printing mechanism and movable totalizer are retained, and in addition a plurality of special transaction totalizers are provided. Any one of the transaction totalzers may be indirectly actuated through the medium of. the racks above referred to. For this purpose the racks are provided with ,an additional set of teeth meshing with pi .hns connected to actuating segments for the multiple totalizers.

The multiple totalizers are carried by a rotatable reel having a geared connection to a setting lever by which the reel may be differentially rotated for the purpose of positioning a desired totalizer opposite the ac, tuating segments. The construction of the totalizer reel, the totalizers carriedthereby and suitable carrying' mechanism for vthe totalizers is substantially shown and described in the United States Patent 'to T homas Carroll No. 703,639.

The driving mechanism of the machine vis adapted t0 move the main totalizer over the racks and to mesh, the selected one of the homere 'loialixers `with the actuating gears, and Jrhen to restore the se ments to 'toe imrmal aero position -roln whicn they were z'noicd by the setting levers. he ret rn moven'ient of the segments effects the desired rotation oit' the totalizer elementsr The invention relates n'incinally to the dit" zrenlial mechanism en ploye for actuating lhe multiple iotaluzers. r,lhr' driere'utial meifhanisin includes a novel conneclion between the aforesaid pinicns, meshing; with the racks and the totaliser actua ing segment gears, whereby on the rcstorinlgr movement olf the segments, the pinions inekej and setting-leviers .are not disturbed, but after the toiaiizcr is actuated it is moved out o? mesh, and the segments are returned to the position to which they were set by the setting levers By this arrangement it is possible to repeat ihe same operation as 'Eten as desired without requiring readjustn ent o'l the setting lev s The particular' means employed to elfe the above object will be fully degcrihed with reference to the vec/mais7mm-The drawings shov7 a manualry opera-Lied drivingr mechanism consisting of a crank 8O (Figa 5) .rigid with a pinion 81 and journalcd on a stub shaft 82. The crank geared to the main drive shaft by the pinion S1 meshing with an intermediate gear S3, in turn meshing with a pinion 84 fast to a pinion 85 meshing,` with a pinion 86 fast to the main drive shaft. lThe gearing such that two rotations of the crank are requiredto ell'ect one rotation of drive shait 59.

Setting' elcmccas.--'l `he controlling mechanism for the machine is positioned by a plurality of value setting' levers 1 l. and a special totalizer reel setting lever 2 (Figs. 5 and). The setting levers 1 are each provided with rack teeth E meshing with pinions Ll fast to a shaft 5 and to sleeves il surrouding shaft @n this shaft and the sleeves are rigidly mounted value type Wheels "Y, therefore adjustment oi the setting levers 1 sets the type wheels in correspondence. The type Wheels are provided with two sets of characters so that double imyressions may he laken of amounts determined by the setting of levers 1. The im- Ipression mechanism is omitlcd from the drawings but is described in. the aforesaid 'raient to Carroll No. 75lol14 L 1Cor the purpose o'lf sailing main racks 8, which serve to communicate .movement oi' the levers to the accounting; mechanisms, the loverr` 'l provided with a second sel'v ci" rack @cth l) i,iesl-.ina' with teeth 10 in the recio; ,lhe racks S have teeth l1 meshing with pinions 1S: last ioval indicators 13 thereby serving to rola l c indicators 1l?? according to the ad' unen't or he levers Secured to the racks 8 are main totalizer controlling racks 14, normally out of cooperative relation with ajnaln or cash totalizer 15, and moved into operative relation with the same by adjustment oli the levers 1. vFor communicating movement of the levers 1 to the operating mechanism for the multiple or reel 't-otalizcrs, the racks S carry a set of rack teeth 1G meshing With pinions 17 loose on a supporting shaft 1.8 but rigid with notched disks 19. Pawls 2O pivoted to yokes E21 vnormally rest in notches 22 in the disks 19 and thus normally serve to communicate movement rom'the pinions 17 to the yoke's 2l. The yokes l (Fig. 7) are secured Ato sleeves 23 which carry rigidly multiple totalizer actuating segments 24. The pawls 2O are compelled to remain in enga-gement with the notches in disks 19 by circular arms 133 against which the paWls ride. Therefore movement of disks 19 by the hand levers 17 serves to move the awls 2O and the actuating segments 24 di ,erentially, but this `hand operated movement is not employed to actuate 'the multiple totalizers as too much load would be throvvnfon the levers 1. To actuzn'e the totalizers, the arms 133 are given an c 'cursion of invariable extent at each operation o'f the main handle, around the shaft 18 and during this' movement they pick up all the pawls and return them to normal zero position, and then restore them tothe previous differential seltinv.

Df/yjfev'catz'a Wwcham'sm for he multiple zfofzlieers.-After the totalizer is meshed with the segment gears 24 shaft 18 is oscillaied hy a segment gear 126 (Fig. 3) pivoted oy a pin 127 to a fixed bracket 128l and provided with a roller 129 extending into a groove 130 in a disk 131 fast to drive shaft 59. ',lhe segment gear 126 meshes with a pinion 132 'fast to shaft 18, and thus oscillation o ille segment gear 126 by the groove engagement of shoulders 13aL with the pawls.. 'ihe shoulders 134i are so cut as to have a,

By this' means the gian-ls 2() are disconnected from disks 1f) leavi1i;"thepinions 1'?, racks S and levers l. in

their adjustedposition while the pawls arc (.-arrie-d hack 'to normal position, thus through the yokes E21 and segments 2li, causinfr the desired difierenti-l relation or' the selected totalizer on reel 31. During the ref turn movement of pawls 20 disks 19 serve to prevent disengagement of the awls from arms 133. Cam groove 130 is so orined that pawls 20 are held in their normal positions for a time suicient to permit unmeshing of the selected totalizer by returning the reel 31 to its lower-position (Fig. 4' under Vthe action of cani groove 124. A ter the unmeshing of the totalizer, shaft 18 is 'rocked back to normal position by the action of cam groove 130,thus eausi all of the arms 188 to be carried to norma position, se shown in Fig. 3, and the paw'ls 20, yokes 21, and totalizer Aactuators 24 to be restored `to the position to which vthey were adjusted by evers 1. When the -awls 20 arrive at such adjusted positions t eir inclined 137 engage inclined shoulders 138 of 4disks 19, an by such e agement are rocked intothe notches 22 of t e disks and so become disconnected from arms 133 which independ .machine.

' Multe' Ze totaZisef/af-The general arrangement o rthe multiple totalizers and the setting mechanism therefor has been pointed out. A selected totalizer is moved into mesh with segment gears 24 '(Fig. 5) by' bodily moving the reel 31 upward. For this purpose the shaft 110, w is carried by slides 111. The slides are pro vided with flanges r112 and 113 iittin in channels 114 andll in brackets 116 an 117 secured to a side frame 118. One of the slides 111 is provided with a pin 119 extending through a slot 120 in a bell 'crank lever 121, pivoted to the frame 118 by a pin A122 and having a roller .|123 extending into a oove 124 in a disk-125 fast to the main rive shaft 59. The groove 124 is so formed that the bell crank lever 121 will he rocked iipwardly, thus meshin the selected totalizer 35 with the actuating racks 24, at the beginning of rotation of shaft 59. The totalizer is heldin meslrlong enough to permit estorationof the actuators 24 to zero posi- (Figs. 5 an tion, as described farther on.

The multi le totalizer reel setting lever 2 6) is secured to aishort shaft 25, to whichis rigidly secured a segment gear 26 meshing with a segment gear 27 rigid on a shaft'28 with a forked arm 29.V

y A rack 30 foirt'a'ting the transaction totalli'er reel 314 meshes with a pinion 32 fast to lthe reel and is fslidably mounted on pins 33 ich supports the reel,-

a'nd also carries a pin 34 passing through the fork in arm 29. This arrangement results in differential movement of the lever 2 being communicated to theJtotalizer reel 31 through the segments 26 and 27, arm 29 and rack 30, and thus any desired totalizer 35 on the reel may be positioned near the actuators M.

In order 4that the operator ma know when the lever 2 is properly adjuste so that the desired totalizer is opposite the actuators 24, the lever 2 carries a spring actuated plunger 36 co-acting with notches 37 in a segmental plate 38S rigidly secured byl pins 39 to amachine side-frame 40. The lunger 36 is mounted on a short late 41 u by links 42 from pins 43 on t e lever 2. n'he lever 2 carriesa pin 44 on which is pivoted a thumb grip 45 having an arm 46 or engaging a lug 47 of the p ate 41. By forcing the thumb grip 45 toward lever 2 the arm 46 pushes plate 41 inwardly thereby 'ca ing p unger B6 out of one of 'the note es 87 and thus rmits setting movement of lever 2. T e pl er 86 has a shoulder 48 extending across t e front edge 49 of a curved plate 50 pivot/ed by pins 51 to a pair of arms 52, ivoted on the machine frame by pins 39 an pivoted together by a4 in 53 carried by one of the arms and-passmg through a slot in the other. A 1n 54l on theilower arm 52 passes through a ork in a bell-crank lever 55 pivoted to the frame 40 by a pin 56 and provided at its'rear end with a locking nose 57 co-acting with a notched disk 58 fast to the main drive shaft 59 of the machine. A spring 60 is extended between a pin 61 on frame 40 and a pin 620m bell crank lever 55 and normally Serves to hold the bell crank lever,the arms 52, plate 50, plunger 36 and thumb grip 45 in thel lien the thumb grip is depressed shoulder i .48 of plunger 36 forces plate 50 rearwardly thereby rockingv the arms 52 rearwardly and thus, through the pin 54, operating bell crunk lever 55 to carry itsnose 57 into the notch in disk 58. The machine is thus locked against operation while lever 2 is being adjusted from one position to another, as it is impossible to adjust lever 2 without depressing thumb grip 45 and bell crank lever 55 cannot return to its unlocking positionuntil the thumb grip is released, permitting plunger 36 'to enter one of the notches 37. l'f the lever 2 is set to a posi? tion such that the plunger 36 is between two of the'notchcs 37, no totalizerwill be opposite actuators 24 and plate 38 serves to hold the plunger 36 in its inner position and consequently the hell'crank lever 55 in its locking position` Main triolisme-The main totalizer l5 4(Fig. 1) is identical in construction with 50 which carry the transfer pawls 10S.

patent to Carroll, No.75111, and will be but hriey described. This totalizer consistsrof a plurality of pinions 87 `loosely journaled on a shaft 88 jonrnaled in a trame` 89. The totalizer carrying frame. S9 is provided with rollers fitting in channels 90 in a traine 91 hung from a rod 92 carried by ears 93 on a tie bar 941. The frame S9 is normally supported in its upper position, as

w shown in Fig. 1, hy pitmen 95, pivoted at their rear ends on a rod 9G supported in brackets 97, and at their forward ends pron vided with slots 98 through which a tie bar 99 of the totalizer frame extends. The pit men 95 are provided with rollers 100 eX- tending into cam grooves 101 in disks 102 tast to the drive shaft 59. The' grooves 101 are so formed that upon rotation ot' drive shaft 59, the pitmen 95 are rocked down- Wardly around the rod 9G thereby causing the tot-alizer frame 89 to be moved downwardly. The tot-alizer remains at rest in its lowered position for a short time, after which the grooves 101 return the pitmen 95 to normal position thereby returning the totalizer 89 to normal position. During the downward movement of trame 89 the totalizer pinious 87 engage and are rotated by such of the racks 14 as have heen moved upwardly by adjustment of levers 1, but in order not to rotate the totalizer upon Jthe return n'iovement of frame 89 the frame 91 is pivotally connected to pitmen 103 reciprocated by cam grooves 104 in disks 102.

Thegrooves 104 are so formed as to rock the frame 91 rearwardly around the pivot 92 betere the downward movement of the totaliZe'r, thus bringing' the totalzer pinions 87 into cooperative relation with racks 14 so 40 that the same will lie-rotated when the totalizer is moved downwardly. When the totalizer is at rest in its lower position the frame 91 is returned to normal position thus permitting the totalise-,r to be returned to normal position without being reversely rotated by racks 11. During the return ot the number of tiines'the different totalisers of the reel are actuated, a plurality of counters 139, (Fig. 1) one for each totalizer of vthe reel., are mounted on a rod 1.40 carried by brackets 1411 secured to the frame of the machine. The pawls 142, for actuating the counters, are pivoted to levers 14.3 journaled on a rod 144 and having extensions 145 coactin,g with oscillating arms 1416. The arms 146 are Fixed to a snatt 147, journaled in the side trames ctt the machine and Leraars provided with asecond arm 11-8,eXtending into a notch 149 in a pitman 150 (Fig. 2)

actuated by a cam 151 fast on' shaft 59.

Upward movement of the pitman 150 causes the arms 1716 to he rocked downwardly when one of them will engage one of the levers 143. The particular lever which it engages is determined by the setting ot the class of transaction lever `2 for which purpose the transaction lever is rigid with a segment' gear 152 (Fig. 1) meshing with a segment gear 153 fast to shaft 154 carrying rigidly a bevel gear 155 meshing with a bevel gear 156 fast to a short shaft 157. The shaft 157 is journaled in a bracket 158 and carries rigidly a segment gear 159 meshing with curved rack teeth 160 carried by shaft 14"'.

By the above arrangement longitudinal movement of shaft 147 is eifcctedto position the arms 146 above the levers 145. The racl; teeth 160 are curved so that shaft 147 canbe osciilated without disconnecting' the rack 160 from segment gear 159. 1t will be readily understood that the arms 146 are spaced, in accordance with the construction in Patent 703,639, at distances such that only one of them may engage a lever 143 at a time. f

A special transaction indicator G3 is set by lever 2 through a segment gear 61- fast to shaft 25 and meshing with a rack 65 slidably mounted on pins (36 and meshing with a pinion 67 tast to the special indicator. ',lhis indicator is alined in its set position by a spring pressed pawl 68 co-acting with a notched alining disk 69 fast to the indicator.

A special transaction type carrier 70 is set by the lever 2 through a segment gear 71 fast to shaft 25 and meshing with a segment gear 72 fast to a shaft 73, which has rigidly secured thereto a segment gear 711 meshing with a rack 75 provided with teeth 76 meshing with a pinion 77 fast to the transaction type carrier 70. The rack 75 is guided in a vertical direction by pins 78 and 79.

Operation-To enter a transaction in the machine, levers 1 are adjusted according to the amount of the transaction and lever 2 is adjusted according to the class ot transaction thereby rotating reel 3l to position the desired transaction totalizer o posite actuators 2li. The levers 1 througi rack teeth 3 set the type carriers 7 and tl'irou'gh rack teeth 9 racks 8 and through the racks 3 rotate the value indicators 13 to the desired positions and also the pinions 17, and through these pinions, disks 19 fast thereto, pawls 20, and yoltes 21, differentially set the transaction totalizer actuators 24. rllhe lever' 2 sets the reel 31 through the segment `gear 2G, (Fig. 5) tast to lever 2 and meshing with segment gear 27, to which is secured arm 29 :tor reciprocating rack 30 lto this rack meshing with the pinion 32 fast' to the reel 31. Lever 2 also sets the transaction indicator 63 (F ig. 6) through the segment gear 64 meshing with rack 65 which in turn meshes with the pinion 67 fast to the transaction indicator. The transaction type carrier 70 is Set through the medium of segment gears 71, Z2 and 71, rack 75 and pinion 77. AAfter the levers 1 and 2 are adjusted as desired, crank "(Fig. 5) is twi rotated thus causing one rotation of shaft 59. This shaft, through the cam disk 125, oscillates bell crank lever 121, thereb meshing the selected special totalizer Witl the actuators 24, and after thetotalizer is meshed, through the cam disk 131 (Fig. 3) oscillates segment fgear 126 thereby oscillating shaft 18 and the curved arms 133. Then notches 136 in the curved arms arrive opposite the ends of pawls .20 in whatever position the pawls have been adjustedl to, shoulders 13e of the arms cam the pawls out of engagement with disks 19 and into engage ment with the notches 136. During the further movement of arms 133 the pawls are carried back to their normal positions, thereby returning the actuators 21 to their normal positions, and differentially rotating the selected totalizer as desired. While the actuators 24 are at rest in their normal posi tions cam disk 125 (Fig. 5) disengages the transaction totalizer from actuators 21 after which segment 126 (Fig. 3) is restored to normal position thus returning the curved arms 133 to normal position. During the return of curved arms 133, when pavvls 2O arrive opposite notches in disks 19, shoul-I ders 13S of the disks engage the inclined 13T ot' the paivls, thereby rocking the parvis out of engagement with the arms 133 and into engagement 1with the notches in disks 19, thus leaving the pau'ls in the position to which they were adjusted by'lcvers 1. During the operation of the selected transaction totalizer the main totalizer 15 is actuated to a similar extent by its reciprocation over racks v11 under the action of pitmen (Fig, 1).

As before stated, the invention relates mainly to the differential mechanism for actuating the multiple totalizers, and it is .ing disengaged from said diierentially movable member; and means for oscillating said plate anl invariable extent thereby causin the pawl to enter said notch and move wit the 'plate to itsy original position and back again. y
